FEEDING MECHANISM FOR SOUND-BOXES.

Application filed October Be it known that I, \Vnmmu \V. Zaonnr, a citzen of the United States, residing in the city and county oflhiladelphia, State of Pennsylvania, have invented a new and usefulFecdmg Mechanism for Sound- Boxcs, of which thefollowing is aspecification.

This invention relates to an improvementin sound recording andreproducing machines and relates more particularly to a mechanism forcausing the sound lack of such a machine to move across 'the face of asound record independently of andin unison with the movement of thegroove of the record.

In machines of this character as heretofore constructed, it has beencustomary for the sound box to be driven or fed across the record by thegrooving therein, the result of which has been a wearing away of thesound wave impressions causing notonly a gradual loss of tone qualitybut also a scratching sound and other unpleasant noises to mar the toneproduced.

Figure 1 represents a sect-ional elevation of a machine embodying myinvention. Fig. 2 represents a section on linen-01; Fig. 1. Fig. 3representsa plan of Fig. 1.

For the purpose of illustrat-ingmy invention, I have shown in theaccompanying drawings one form thereof which is atresent preferred byme, since the same has been found in practice to give satisfactory andreliable results, although it is to be understood that the variousinstrumentalities of which my invention consists can be variouslyarranged and organized and that my invention'is not limited to theprecise arrangement and organization of these instrumentalities asherein shown and described.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings, 1 designates the casing of asound reproducingmachine the same having a motor 2 therein of the usual construction ofwhich 3 designates a driving gear to which in the present instance, Ipreferably connect my novel oper- Iaiting means for the movement of thesound t-"designates the sound box carryin theusual needle 5 and securedby a ivota con- I nection (5 to the supporting tubu ar memberSpecification of Letters Patent.

7 'This arm 7 is movably attached to a suitable bracket 8 and positlonedto receive the amplifying horn, as will be readily-understood, theattaching means preferred cousistlng of a swinging joint 9 in order thatthe arm 7 may be moved readily over the record or swung to one side asthe case may be.

10 designates a belt provided in the present instance with perforations11. adapted to engage the teeth. 12 of a pinion 1? suitably mounted upona spindle lei secured in standards 15. These standards 15 are secured inany suitable manner to the casing l and form with a. set mld pair ofstandards 16 a supporting framework in which the belt 11) is mounted andsuitably guided by means of the rotatably mounted guide wheels 17. aswill be apparent. The belt 10 is positioned adjacent and preferablybeneath the arm 7 so that as the latter rests thereon the friction'between the two is sutiicieht' to carry the arm v7 across the face of arecord with the movement of the belt, the travel of the box 4 beingsubstantially synchronous with the sound waves of the groove of therecord.

Any suitable gearing may he provided for driving the spindle 1+ toactuate the belt 10 it. being 0. course.understood that the gearing muste so designed and constrm-ted as to producean exact and accuratemovement of the belt-10. As here shown, the gearing consists of a pinion18 suitably mounted upon the spindle 14 and in mesh with a gear 19'rotatabl y mounted on the casing and havingsecured. thereto a secondgear 20 which is in mesh with a pinion 21 likewise rotatably mountedupon the casing 1 and having socured thereto a gear 22 cooperating withthe pinion 23 to receive motion from the gear 24. which is driventhrough the medium of a pinion 25 from the gear 3.

It will of course be apparent that the record spindle 26 is driven fromthe motor 2.at a certain speed and in order that the needle 5 of thesound box travel in coincidence with the sound groove a very careful andexact adjustment of theseveral gears 18 to 25 inclusive must be made inorder to transmit suitable movement to the belt 10.

Itwill be seen that the movement of the belt 10 is necessarilya veryslow one and the friction due to the weight of the arm 7 is suflicientto carry the latter along with the belt 10 and over the face of therecord with while the unpleasant noises usually given out aresubstantially done away with. I

It will now be apparent that I have devised a complete unitary structurewell adapted for the purpose intended and which is'simple in operationand construction, eliminates substantially all of the wear upon thesound record, reduces the scratching and drag of the :needle and gives aclear, pure tone with a maximum of volume.

It will now be apparent'that I have devised a novel and usefulconstruction which embodies .the features of advantage enumerated asdesirable in the statement of the invention and the above descriptionand while I have in the present instance shown .and described apreferred embodiment thereof which has been found in practice to givesatisfactory and reliable results, it is to be understood that the sameis susceptible of modification in various particulars without departingfrom the spirit or scope of the invention or sacrificing any of itsadvantages.

Having thus described my invention, what I claim as new and desire tosecure by LettersPatcnt, is l 1. In a sound recording and reproducingmachine, an arm suitably-mounted for swing.- ing movement, a sound boxcarried by said arm, a belt suitably mounted to support said arm, amotor, and driving means between said motor and belt. I

2. In a sound recording and reproducing machine, an arm suitably mountedfor swinging movement, a sound box carried by said arm, a belt suitablymounted to support sound box carried by said am, a framework carried bysaid casing, a plurality of uide wheels rotatably .mounted in saidramework, a belt contacting with said guide wheels and positionedto'support said arm, a motor, and driving means between. said motor andsaid belt.

4. In a sound recording and reproducin machine, a casing, an armsultably mounte for swinging movement relative thereto, a

sound boa carried by said arm, a framework carned by said casing, ashaft in said framework, a gear carried by said shaft, a plurality of,uide wheels mounted in said framework a j acent said gear, a belt havinga plurality of openlngs'therein adapted to engage said gear and passingover said guide wheels, a motor, and means between said shaft andlmotorto drive said shaft at a-predetermined speed.

5. In a sound recording and reproducing machine, a casing, an armsuitably mounte 1 for swinging movement relative thereto, a sound boxcarried by said arm, a frame work carried by said casing, a shaft insaid,

framework, a gear carried by said shaft, a

framework adjacent said gear, a belt having a plurality of openingstherelnadapted to engage said gear and passing over said guide wheels, amotor, and means between said shaft and motor to proportion the movementof said belt relative to the turning movement of a sound record drivenby said motor.
